| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 2 | Fecal microbiota transplantation cured epilepsy in a case with Crohn's disease: The first report显示文摘Fecal microbiota transplantation(FMT)is a promising strategy that involves reconstruction of gut microbiota.Recently,it has been considered as a treatment of Crohn’s disease(CD)and certain neurological diseases.Here,to the best of our knowledge,we report the first case that used FMT to achieve remission of intestinal and neurological symptoms in a girl with CD and a 17-year history of epilepsy.During the 20 mo of follow-up,FMT has proved its efficacy in preventing relapse of seizures after withdrawing the antiepileptic drugs.Furthermore,this finding highlights the role of microbiota-gut-brain axis and inspires a novel treatment for epilepsy through remodeling gut microbiota. | Zhi He Bo-Ta Cui Ting Zhang Pan Li Chu-Yan Long Guo-Zhong Ji Fa-Ming Zhang | 2017 | World Journal of Gastroenterology2017，23，19： | 37 |

| 4 | Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy. | Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen | 2021 | Cancer Communications2021，41，11： | 29 |
| 5 | Rapid quantification of semen hepatitis B virus DNA by real-time polymerase chain reaction显示文摘AIM: To examine the sensitivity and accuracy of real-time polymerase chain reaction (PCR) for the quantification of hepatitis B virus (HBV) DNA in semen.METHODS: Hepatitis B viral DNA was isolated from HBV carriers' semen and sera using phenol extraction method and QTAamp DNA blood mini kit (Qiagen, Germany). HBV DNA was detected by conventional PCR and quantified by TaqMan technology-based real-time PCR (quantitative polymerase chain reaction (qPCR)). The detection threshold was 200 copies of HBV DNA for conventional PCR and 10 copies of HBV DNA for real time PCR per reaction.RESULTS: Both methods of phenol extraction and QIAamp DNA blood mini kit were suitable for isolating HBV DNA from semen. The value of the detection thresholds was 500 copies of HBV DNA per mL in the semen. The viral loads were 7.5×107 and 1.67×107 copies of HBV DNA per mL in two HBV infected patients' sera, while 2.L4×105 and 3.02×105 copies of HBV DNA per mL in the semen.CONCLUSION: Real-time PCR is a more sensitive and accurate method to detect and quantify HBV DNA in the semen. | Wei-Ping Qian Yue-Qiu Tan Ying Chen Ying Peng Zhi Li Guang-Xiu Lu Made C.

| 6 | Single-incision vs three-port laparoscopic cholecystectomy:Prospective randomized study显示文摘AIM:To compare the clinical outcome of single-inci-sion laparoscopic cholecystectomy(SILC)with threeport laparoscopic cholecystectomy(TPLC). METHODS:Between 2009 and 2011,one hundred and two patients with symptomatic benign gallbladder diseases were randomized to SILC(n=49)or TPLC (n=53).The primary end point was post operative pain score(at 6 h and 7 d).Secondary end points were blood loss,operation duration,overall complications,postoperative analgesic requirements,length of hospital stay,cosmetic result and total cost.Surgical techniques were standardized and all operations were performed by one experienced surgeon,who had performed more than 500 laparoscopic cholecystectomies. RESULTS:One patient in the SILC group required conversion to two-port LC.There were no open conversions or major complications in either treatment groups.There were no differences in terms of esti-mated blood loss(mean±SD,14±6.0 mL vs 15±4.0 mL),operation duration(mean±SD,41.8±17.0 min vs 38.5±22.0 min),port-site complications(contusion at incision:5 cases vs 4 cases and hematoma at inci- sion:2 cases vs 1 case),total cost(mean±SD,12 075 ±1047 RMB vs 11 982±1153 RMB)and hospital stay (mean±SD,1.0±0.5 d vs 1.0±0.2 d),respectively. TPLC had a significantly worse visual analogue pain score at 8 h after surgery(mean±SD,3.5±1.6 vs 2.0 ±1.5),however,the scores were similar on day 7(mean ±SD,2.5±1.4 vs 2.0±1.3).Cosmetic satisfaction, as determined by a survey at 2 mo follow-up favored SILC(mean±SD,8±0.4 vs 6±0.2). CONCLUSION:SILC is a safe and feasible approach in selected patients.The main advantages are a better cosmetic result and less pain. | Ming-Xin Pan Ze-Sheng Jiang Yuan Cheng Xiao-Ping Xu Zhi Zhang Jia-Sheng Qin Guo-Lin He Ting-Cheng Xu Chen-Jie Zhou Hai-Yan Liu Yi Gao | 2013 | World Journal of Gastroenterology2013，19，3： | 24 |

| 8 | Cap-assisted endoscopic sclerotherapy for hemorrhoids: Methods, feasibility and efficacy显示文摘AIM: To evaluate the methodology, feasibility, safety and efficacy of a novel method called cap-assisted endoscopic sclerotherapy(CAES) for internal hemorrhoids.METHODS: A pilot study on CAES for grade Ⅰ to Ⅲ internal hemorrhoids was performed. Colon and terminal ileum examination by colonoscopy was performed for all patients before starting CAES. Polypectomy and excision of anal papilla fibroma were performed if polyps or anal papilla fibroma were found and assessed to be suitable for resection under endoscopy. CAES was performed based on the requirement of the cap, endoscope, disposable endoscopic long injection needle, enough insufflated air and sclerosing agent.RESULTS: A total of 30 patients with grade Ⅰ to Ⅲ internal hemorrhoids was included. The follow-up was more than four weeks. No bleeding was observed after CAES. One(3.33%) patient claimed mild tenesmus within four days after CAES in that an endoscopist performed this procedure for the first time. One hundred percent of patients were satisfied with this novel procedure, especially for those patients who underwent CAES in conjunction with polypectomy or excision of anal papilla fibroma.CONCLUSION: CAES as a novel endoscopic sclerotherapy should be a convenient, safe and effective flexible endoscopic therapy for internal hemorrhoids. | Ting Zhang Li-Juan Xu Jie Xiang Zhi He Zhao-Yuan Peng Guang-Ming Huang Guo-Zhong Ji Fa-Ming Zhang | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，19： | 22 |
| 9 | Clinical and experimental study on regional administration of phosphorus32 glassmicrospheres in treating hepatic carcinoma显示文摘AIM To study the therapeutical effectiveness, dosage range and toxic adverse effects of domestic phosphorus 32 glass microsphere and evaluate its clinical significance. METHODS Ⅰ. Fifty two BALB/*!c tumor bearing male nude mice were allocated into treatment group( n =38) and control group( n =14). In the former group different doses of 32 P GMS were injected into the tumor mass, while in the latter 31 P GMS or no treatment was given. The experimental animals were sacrificed in batches, and then the tumors and their nearby tissues were examined by light and electron microscopy. Ⅱ. Through selective catheterization of hepatic artery, 32 P GMS was infused to 5 healthy domestic pigs in a dosage equivalent to the therapeutic dose for human being, and 31 P GMS was infused to another 5 healthy domestic pigs. Two pigs infused with contrast medium served as whole course blank controls. One pig from each group was surrendered to euthanasia at week 1, 4, 8 and 16 respectively. The ultrastructural histopath ological changes in liver tissues taken from different sites were evaluated semiquan titatively. Ⅲ. One hundred and twenty seven times of 32 P GMS intrahepatic artery interventional therapies were performed on 93 patients with hepatic carcinoma, including 79 cases of primary hepatic carcinoma and 14 cases of secondary hepatic carcinoma. 32 P GMS ( n =30), and group B, 32 P GMS and half dose of trans hepatic artery embolization (TAE) ( n =49) , and 18 patients with HCC by TAE only as control group C. Fourteen patients with secondary hepatic carcinoma were treated in the same way as group B or C. RESULTS Ⅰ. Comparing with the control group, the treatment group of tumor bearing nude mice attained the tumor inhibition rates of 59 7%-93 7% ( F =579 62, P <0 01) at 14*!d . At an absorbed dose of 7320Gy, the tumor cells were completely destroyed. When the absorbed doses ranged from 1830Gy to 3660Gy, most of the tumor cells showed the evidences of injury or necrosis, but there appeared some well differentiated tumor cells and enhanced effect of the autoimmunocytes. At an absorbed dose of 366Gy or less, some tumor cells still remained active proliferative ability. The definite anticancer effect appeared as early as 3d after intratumoral injection of 32 P GMS. Ⅱ. The cumulative amount of 32 P GMS in the target tissue after trans hepatic artery instillation attained more than 90% of the total dose administrated. Semiquantitative analysis of ultrastructral morphology in the experimental group showed no statistical difference between the nuclear abnormality (N abn ) and mitochondrial variability (M var ) at week 1 or 2, but revealed prominent difference (χ 2=6 70-9 68, P <0 01 , χ 2=65 09-115 09, P <0 001 ) as compared with those in the other groups. In the experimental group the N abn in tissues showed no significant difference between week 8 and week 16. No apparent changes were found in the stomach, spleen, kidney and lung tissues of the experimental pigs. Ⅲ. The therapeutical results of HCC patients in group A were closely approximated to those of group C, no hematological toxic side effects were noted, and the systemic reaction was mild. In some patients 2*!mos - 3*!mos after treatment some secondary foci appeared around the periphery of the primary lesion. In general better effectiveness was obtained in patients with small lesion. After analyzing by RIDIT method, the therapeutic result in group B was significantly better than that in group C, and secondary foci around the original lesion were rarely seen at 3*!mos after treatment. In group C the collateral circulation was reestablished along the periphery of primary foci and the secondary foci appeared more frequently, and required to undergo several courses of treatment. In group B, 4 cases of HCC were treated surgically as their mass decreased in size after 32 P GMS treatment. | LIU Lu, JIANG Zao, TENG Gao Jun, SONG Ji Zhi, ZHANG Dong Sheng, GUO Qing Ming, FANG Wen, HE Shi Cheng and GUO Jin He | 1999 | World Journal of Gastroenterology1999，5，6： | 21 |
| 10 | Effects of Short-Term Forest Bathing on Human Health in a Broad-Leaved Evergreen Forest in Zhejiang Province,China显示文摘Objective To investigate the effects of short-term forest bathing on human health.Methods Twenty healthy male university students participated as subjects and were randomly divided into two groups of 10.One group was sent on a two-night trip to a broad-leaved evergreen forest,and the other was sent to a city area.Serum cytokine levels reflecting inflammatory and stress response,indicators reflecting oxidative stress,the distribution of leukocyte subsets,and plasma endothelin-1 (ET-1) concentrations were measured before and after the experiment to evaluate the positive health effects of forest environments.A profile of mood states (POMS) evaluation was used to assess changes in mood states.Results No significant differences in the baseline values of the indicators were observed between the two groups before the experiment.Subjects exposed to the forest environment showed reduced oxidative stress and pro-inflammatory level,as evidenced by decreased malondialdehyde,interleukin-6,and tumor necrosis factor α levels compared with the urban group.Serum cortisol levels were also lower than in the urban group.Notably,the concentration of plasma ET-1 was much lower in subjects exposed to the forest environment.The POMS evaluation showed that after exposure to the forest environment,subjects had lower scores in the negative subscales,and the score for vigor was increased.Conclusion Forest bathing is beneficial to human health,perhaps through preventive effects related to several pathological factors. | MAO Gen Xiang LAN Xiao Guang CAO Yong Bao CHEN Zhuo Mei HE Zhi Huat LV Yuan Dong WANG Ya Zhen HU Xi Lian WANG Guo Fu YAN Jing | 2012 | Biomedical and Environmental Sciences2012，25，3： | 20 |
| 11 | 3D printing of bone tissue engineering scaffolds显示文摘Tissue engineering is promising in realizing successful treatments of human body tissue loss that current methods cannot treat well or achieve satisfactory clinical outcomes.In scaffold-based bone tissue engineering,a high performance scaffold underpins the success of a bone tissue engineering strategy and a major direction in the field is to produce bone tissue engineering scaffolds with desirable shape,structural,physical,chemical and biological features for enhanced biological performance and for regenerating complex bone tissues.Three-dimensional(3D)printing can produce customized scaffolds that are highly desirable for bone tissue engineering.The enormous interest in 3D printing and 3D printed objects by the science,engineering and medical communities has led to various developments of the 3D printing technology and wide investigations of 3D printed products in many industries,including biomedical engineering,over the past decade.It is now possible to create novel bone tissue engineering scaffolds with customized shape,architecture,favorable macro-micro structure,wettability,mechanical strength and cellular responses.This article provides a concise review of recent advances in the R&D of 3D printing of bone tissue engineering scaffolds.It also presents our philosophy and research in the designing and fabrication of bone tissue engineering scaffolds through 3D printing. | Chong Wang Wei Huang Yu Zhou Libing He Zhi He Ziling Chen Xiao He Shuo Tian Jiaming Liao Bingheng Lu Yen Wei Min Wang | 2020 | Bioactive Materials2020，5，1： | 20 |
| 12 | Aero-optical aberration measuring method based on NPLS and its application显示文摘The existing methods for measuring aero-optical aberration suffer from several problems,such as low spatiotemporal resolution,sensitivity to environment,and integral effects.A new method for measuring aero-optical aberration of supersonic flow is proposed.Based on the self-developed measuring method of supersonic density field,the wavefront aberration induced by a cross-section of supersonic flow field could be measured by ray-tracing.Compared with other methods,the present one has three significant innovations:(1) high spatiotemporal resolution.Its time resolution is 6 ns,and the spatial resolution can reach up to micrometers;(2) it can avoid the integral effects and study the wavefront aberration induced by the flow field of interest locally;(3) it can also avoid the influence from the test section wall boundary layers and environmental disturbances.The present method was applied to supersonic flow around an optical bow cap.The results of high spatiotemporal resolution reveal fine wavefront structures,and show that shock waves,expansion waves and turbulent boundary layers have different impacts on the wavefront aberration. | YI ShiHe TIAN LiFeng ZHAO YuXin HE Lin CHEN Zhi | 2010 | Chinese Science Bulletin2010，55，31： | 20 |
| 13 | Visualization of coherent structures in a supersonic flat-plate boundary layer显示文摘Flow in a flat-plate zero-pressure-gradient boundary layer at Mach 3 was visualized via nanoparticle-based planar laser scattering (NPLS). Coherent structures such as an individual hairpin vortex and hairpin packet were identified in the streamwise-wall-normal plane on the basis of the now accepted hairpin model. Λ-shaped vortices were found in a staggered pattern in the stream-wise-spanwise plane, which indicated H-type transition in the present experiments. This is the direct evidence (in the form of flow visualization) of such coherent structures in a supersonic boundary layer. A series of NPLS images taken in streamwise-spanwise planes at different heights is presented, and the three-dimensional structures of the supersonic boundary layer agree well with the hairpin model. | HE Lin YI ShiHe ZHAO YuXin TIAN LiFeng CHEN Zhi | 2011 | Chinese Science Bulletin2011，56，6： | 19 |
| 14 | A Chromosome-Scale Genome Assembly of Paper Mulberry(Bmussonetia papyrifera)Provides New Insights into Its Forage and Papermaking Usage显示文摘Paper mulberry(Broussonetia papyrifera)is a well-known woody tree historically used for Cai Lun papermaking,one of the four great inventions of ancient China.More recently,Paper mulberry has also been used as forage to address the shortage of feedstuff because of its digestible crude fiber and high protein contents.In this study,we obtained a chromosome-scale genome assembly for Paper mulberry using integrated approaches,including Illumina and PacBio sequencing platform as well as Hi-C,optical,and genetic maps.The assembled Paper mulberry genome consists of 386.83 Mb,which is close to the estimated size,and 99.25%(383.93 Mb)of the assembly was assigned to 13 pseudochromosomes.Comparative genomic analysis revealed the expansion and contraction in the flavonoid and lignin biosynthetic gene families,respectively,accounting for the enhanced flavonoid and decreased lignin biosynthesis in Paper mulberry.Moreover,the increased ratio of syringyl-lignin to guaiacyl-lignin in Paper mulberry underscores its suitability for use in medicine,forage,papermaking,and barkcloth making.We also identified the rootassociated microbiota of Paper mulberry and found that Pseudomonas and Rhizobia were enriched in its roots and may provide the source of nitrogen for its stems and leaves via symbiotic nitrogen fixation.Collectively,these results suggest that Paper mulberry might have undergone adaptive evolution and recruited nitrogen-fixing microbes to promote growth by enhancing flavonoid production and altering lignin monomer composition.Our study provides significant insights into genetic basis of the usefulness of Paper mulberry in papermaking and barkcloth making,and as forage.These insights will facilitate further domestication and selection as well as industrial utilization of Paper mulberry worldwide. | Xianjun Peng Hui Liu Peilin Chen Feng Tang Yanmin Hu Fenfen Wang Zhi Pi Meiling Zhao Naizhi Chen Hui Chen Xiaokang Zhang Xueqing Yan Min Liu Xiaojun Fu Guofeng Zhao Pu Yao Lili Wang He Dai Xuming Li Wei Xiong Wencai Xu Hongkun Zheng Haiyan Yu Shihua Shen | 2019 | Molecular Plant2019，12，5： | 18 |

| 16 | Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. | ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang | 2014 | Biomedical and Environmental Sciences2014，27，5： | 17 |
| 17 | Prediction of permafrost changes in Northeastern China under a changing climate显示文摘Northeastern China has the second largest expanse of permafrost in China,primarily known as Xing'an-Baikal permafrost.Located on the southeastern edges of the Eurasian cryolithozone,the permafrost is thermally unstable and ecologically sensitive to external changes.The combined impacts of climatic,environmental,and anthropogenic changes cause 3-dimensional degradation of the permafrost.To predict these changes on the southern limit and ground temperature of permafrost in Northeastern China,an equivalent latitude model (ELM) for the mean annual ground surface temperature (MAGSTs) was proposed,and further improved to take into account of the influences of vegetation and snow-cover based on observational data and using the SHAW model.Using the finite element method and assuming a climate warming rate of 0.048°C a-1,the ELM was combined with the unsteady-state heat conduction model to simulate permafrost temperatures at present,and to predict those after 50 and 100 a.The results indicate that at present,sporadic permafrost occurs in the zones with MAGSTs of 1.5°C or colder,and there would still be a significant presence of permafrost in the zones with the present MAGSTs of 0.5°C or colder after 50 a,and in those of-0.5°C or colder after 100 a.Furthermore,the total areal extent of permafrost would decrease from 2.57×105 km2 at present to 1.84×105 km2 after 50 a and to 1.29×105 km2 after 100 a,i.e.,a reduction of 28.4% and 49.8% in the permafrost area,respectively.Also the permafrost would degrade more substantially in the east than in the west.Regional warming and thinning of permafrost would also occur.The area of stable permafrost (mean annual ground temperature,or MAGT≤-1.0°C) would decrease from present 1.07×105 to 8.8×104 km2 after 50 a,and further decrease to 5.6×104 km2 after 100 a.As a result,the unstable permafrost and seasonally frozen ground would expand,and the southern limit of permafrost would shift significantly northwards.The changes in the permafrost environment may adversely affect on ecological environments and engineering infrastructures in cold regions.Avoidance of unnecessary anthropogenic changes in permafrost conditions is a practical approach to protect the permafrost environment. | WEI Zhi JIN HuiJun ZHANG JianMing YU ShaoPeng HAN XuJun JI YanJun HE RuiXia CHANG XiaoLi | 2011 | Science China Earth Sciences2011，54，6： | 15 |

| 19 | Study on the anticarcinogenic effect and acutetoxicity of liver-targeting mitoxantrone-nanoparticles显示文摘AIM To study the anticarcinogenic effect and acute toxicity of liver targeting mitoxantrone nanospheres. METHODS The anticarcinogenic effect of mitoxantrone polybutylcyanoacrylate nanoparticles (DHAQ PBCA NP) was investigated by using heterotopic and orthotopic transplantation models of human hepatocellular carcinoma (HCC) in nude mice and was compared with mitoxantrone (DHAQ) and doxorubicin (ADR). The acute toxicity of DHAQ PBCA NP lyophilized injection in mice was also studied. RESULTS The tumor inhibition rates of ADR, DHAQ, DHAQ PBCA NP to orthotopically transplanted HCC were 60 07%, 67 49% and 99 44%, respectively, but regard to heterotopically transplanted HCC, these were 80 03%, 86 18% and 92 90%, which were concordant with the results acquired by mitosis counting and proliferating cell nuclear antigen (PCNA). After iv administration to mice with DHAQ PBCA NP, the LD 50 was 16 9*!mg/*!kg ± 3 9*!mg/*!kg , no obvious local irritation was observed and there was no significant damage to the structure of liver cells, and that of the heart, spleen and kidneys. CONCLUSION The effect of DHAQ PBCA NP was significantly higher than that of DHAQ and ADR in the anti orthotopically transplanted HCC and the acute toxicity was relatively low. | ZHANG Zhi Rong, HE Qin, LIAO Gong Tie and BAI Shao Huai | 1999 | World Journal of Gastroenterology1999，5，6： | 13 |
| 20 | Electroacupuncture at ST36 modulates gastric motility via vagovagal and sympathetic reflexes in rats显示文摘BACKGROUND Electroacupuncture(EA) at ST36 can significantly improve gastrointestinal symptoms, especially in promoting gastrointestinal motility. The automatic nervous system plays a main role in EA, but few studies exist on how vagovagal and sympathetic reflexes affect EA to regulate gastrointestinal motility.AIM To study the role of vagovagal and sympathetic reflexes in EA at ST36, as well as the associated receptor subtypes that are involved.METHODS Gastric motility was measured with a manometric balloon placed in the gastric antrum area in anesthetized animals. The peripheral nervous discharge was measured using a platinum electrode hooking the vagus or greater splanchnic nerve, and the central nervous discharge was measured with a glass microelectrode in the dorsal motor nucleus of the vagus(DMV). The effects and mechanisms of EA at ST36 were explored in male Sprague-Dawley rats which were divided in to a control group, vagotomy group, sympathectomy group, and microinjection group [including an artificial cerebrospinal fluid group, glutamate(L-Glu) group, and γ-aminobutyric acid(GABA) group] and in genetically modified male mice [β1β2 receptor-knockout(β1β2^(-/-)) mice, M2M3 receptorknockout(M2M3^(-/-)) mice, and wild-type control mice].RESULTS EA at ST36 promoted gastric motility during 30-120 s. During EA, both vagus and sympathetic nerve discharges increased, with a much higher frequency of vagus nerve discharge than sympathetic discharge. The gastric motility mediated by EA at ST36 was interdicted by vagotomy. However, gastric motility mediated by EA at ST36 was increased during 0-120 s by sympathectomy, which eliminated the delay effect of EA during 0-30 s, but it was lower than the control group during 30-120 s. Using gene knockout mice and their wild-type controls to explore the receptor mechanisms, we found that EA at ST36 decreased gastric motility in M2/3^(-/-) mice, and promoted gastric motility in β1/2^(-/-) mice. Extracellular recordings showed that EA at ST36 increased spikes of the DMV. Microinjection of L-Glu into the DMV increased gastric motility, while EA at ST36 decreased gastric motility during 0-60 s, and promoted gastric motility during 60-120 s.Injection of GABA reduced or increased gastric motility, and reduced the promoting gastric motility effect of EA at ST36.CONCLUSION These data suggest that EA at ST36 modulates gastric motility via vagovagal and sympathetic reflexes mediated through M2/3 and β1/2 receptors, respectively.Sympathetic nerve activity mediated through β1/2 receptors is associated with an early delay in modulation of gastric motility by EA at ST36. | Meng-Jiang Lu Zhi Yu Yan He Yin Yin Bin Xu | 2019 | World Journal of Gastroenterology2019，25，19： | 13 |
